Best Film on Newton's Third Law. Ever.
HTML-код
- Опубликовано: 4 окт 2024
- There is a gravitational force of attraction between the Earth and the moon, but is it mutual? That is, are the forces on the Earth and the moon equal? Most people would say no, the Earth exerts a greater force of attraction because it is larger and has more mass. This is a situation in which Newton's Third Law is relevant. Newton's Third Law says that for every force, there is an equal and opposite reaction force. So the force the Earth exerts on the moon must be exactly equal and opposite the force the moon exerts on the Earth. But how can that be - that the same size force keeps the moon orbiting, but barely affects the Earth? The answer is inertia - the tendency for all objects with mass to maintain their state of motion. Since the Earth has much more mass than the moon, it has greater inertia and therefore experiences much less acceleration for the same amount of force.

This is also my conclusion.

Iwas literally thinking the same thing xD
So priceless

I'd say this is the main reason YT is the best at its game
Same. It was a shock seeing him so young.
And that's why size doesn't matter boys. It's all about the force..
Postermaestro NAILED IT !!
Postermaestro I'm not a scientist tho i really don't understand the newton's law calculating who is attracting who really...... object A attracts object B, what happens? they get closer right? so isn't the gravity force the combined attraction of A and B? i mean we are in space talking about planets and so who's the static parameter: if i pull someone, if i'm heavier, that someone will get moved toward me, or instead i'll be pulled to that person. That notion is only mesurable since we have the static ground to compare who moved toward who, if you remove the ground, we just get closer and on that no matter who pulled harder since the link between us it the pulling force that was enough to counter our combined inertia... or i just didn't got it ^^'
Jack Jack if you and a friend were sitting in separate rafts floating in water holding opposite end of a rope and pulled the rope, you would both move and meet near the middle of where you started. If ten people joined your friends and you pulled the rope, you would move more than them but they would move toward you a some.
In all cases, the tension on both ends of the rope would be equal. You are pulling with the same force that you are being pulled.
Mark Daniel indeed and in that case: what would happen if they (10) were just holding the rope and not pulling and i was pulling it alone? it will for sure result of me getting closer to their spot but they would also move but all of that in slow rate, what i'm trying to poit at is: How could you say the pulling force is from who or who? the generator of that force is a separate thing from the pulling force appliance itself cause if i genenrate 50% of it and the 10 guys in front would each generate 5% it would result 100% for all of us so for my understanding the pulling force applied is one single pulling force applied equaly to 2 masses.
Another question is: As we know a chopper can't move faster than his fan's rolling speed, if it goes 10km/h while it's fan at the edge rotates at 10km/h as well, means one side will travel 20km (opposing wind from speed 10km/h + it's own speed 10km/h) and other will stay static 0km/h (10km/h from moving speed - 10km/h of own backward movement) so now that we are aware that moving around an already moving corp creates such variations, how does the moon follows earth while at a point the inertia of both is down while moon crossing earth's path from front and increased while the moon is crossing from behind? there is more than just gravity and it's not only pulling, i'm wondering if the gravity stream itself can kind of stretch and retract without loosing any force or if the loss from one move isn't increasing another field we don't know yet wich will bend those 2 masses to an almost regular distance, since we can keep track of both earth and moon's paths, i see it more as 2 corps bound to an elastic rope.

He’s literally farming views at this point, after he’s figured out this whole RUclips algorithm. To be quite frank though, he deserves more views
I guess so
Truuuuuuuue
Entirely agreed - however this one felt more towards the clicktrap end of the scale than the perfect legitbait. Not entirely sure I ended the video feeling as satisfied as his more recent videos - but that figures, considering it's a decade old 😊
Agree. Think even he knows this is not the best video about Newton ever. Great to watch young Derek, though!
Yeah I'll grant him that because he still has this innocent curiousity when he tries these things plus I don't feel duped because he gives me a lot back by shamelessly grabbing my attention like that so it's a double win (and it feels more like a running gag by now actually).
And last but not least, his honest intend.
You just know that he doesn't do that to grab money, he really does this to spread his enthusiasm for science, to enrich others and not just himself. So it makes me chuckle how this overambitious squirrel is now hacking itself through every of his videos to spread the love. It's contagious.
And it also puts the true clickbaiter to shame as he beats them in their own game which forces them to become better or fade into unimportance again. It's just perfect on so many levels.

well for most simple physics where you assume everything is a particle and work with at most two dimensions, newtonian physics is more than enough, even in some profession relativity is irrelevant because, while an oversimplification of the natural world, newtonian physics still accurately desribe most of our day-to-day lives.

I'd love to see you interview some engineering and science first year students from college about this.

@@somefreshbread they hit right in the spleen
When I taught physics, the 3rd law was by far the hardest area for removing student's preconceived notions. You just pointed one of them out. The other is that they think that the matching force for my weight, when I'm standing on a floor, is the floor pushing up on me. The first Khan Academy video on N3 even had this wrong, and 10 years later that video is still up. And everybody argued fiercely with me when I tried to explain that the video was wrong.
true
Damn, we need to comment bomb that video. Khan Academy is taken to be the work of God by many.
I think it would've tied it up nicely to finish the ending by adding that now with equal forces acting on the masses, the smaller one accelerates more because it has smaller mass.
Thanks man, this finally helped me understand it
thank you!
If you put a rubber band (or a piece of elastic chord or whatever) around two objects, the pull towards each other is obviously equal. If the objects are the same mass (two identical marbles) they'll move towards each other at the same speed. If you have one huge marble and one smaller one, the bigger one will still move but slower than the smaller one, because of inertia.
A neat way to visualize the concept of gravity and Newton's 3rd law.
This is more interesting than the video 😊
Your spleen is one of the only organs that dose not have a pain center, It's imposible to feel anything there

@@sirewangpho5146 You standing normally on a scale and you standing on a scale which is upside-down ,both show the same weight.

When it comes to gravity I think it is more intuitive for people to see F = ma in the form of F/m = a. That way it looks more like we are solving for a.
I can now feel newton's third law in my spleen. Thank you Veritasium.
The only thing I learned from this video is even if people knew something and be aware of that knowledge at the time of being asked the relative question they could still lack understanding of the knowledge.
*Ah yes gotta love a bit of Newton’s 3rd law in my spleen*
In the case of the Earth and Moon. It's actually not Newton's Third Law that's being invoked. Why? Because, the Third Law is still a Law of *Motion.*
In reality it is just Newton's Universal Law of Gravitation that is needed here, as it states that every particle in the universe, will attract every other particle in the universe with a force... proportional to...blah, blah!
Newton's Third Law only arises when we consider the actual *motion* of the two objects, in orbit around there barycentre. The *Action* is centripetal and is called, *gravity* and the *Reaction* is *inertia* and is called, the *centrifugal* force.
Although, typing this was a complete waste of *absolute* time, as no one will ever read it. Thanks
Nah bro, great explanation. Loved it
@@saksham79 Yeah bro, you're welcome, great reply. Loved it. Although, I'd add that at the centre of the moon the centripetal and centrifugal forces cancel, according to *Newton's Third Law of Motion.* And the moon continues on it's straight line path, at a constant speed, moving on an unaccelerated path, called a geodesic in curved spacetime, because Gravity actually is not a force? And a force is not required to maintain *Motion.* Which is explained in another successful show on this channel. Take care and thanks for the support.
I remember watching this video 8 years ago. It made me love physics way too much that I became a mechanical engineer. No regrets. Old is Gold.
just remember f = ma. if anything my physics teacher tought me, is that every time we need to solve a new problem, just stick in f = ma and see what happens

+Willoughby Krenzteinburg You don't need to rationalize any of it in order to work with it.
Taxtro you kind of do. I can't imagine grasping quantum physics without understanding Newtons third law. In physics, the more advanced concepts require a basic understanding. It's like claiming to be a professional NFL quarterback without knowing how to throw a ball.

Ok is no-one going to talk about how the speed limit is "C" at 2:30
Why would anyone talk? Don't we all know that c is the speed limit of the universe? /s
He was so young ;3
I think most of them probably didn't understand it because they didn't understand "force", which is a technical concept. If you substitute "acceleration", all their replies are accurate.
Yeah, and? Acceleration and force are two different things. That's like asking someone what color the grass is, and when they all answer 'blue', you come in and say, "Yeah, but if you replace "grass" with "sky", they all got it right.
No, they didn't. They all got it wrong. He was referencing the FORCE; not ACCELERATION. Two different things!!!
You said 'force' is a technical concept. Acceleration isn't?!!?? What are you talking about?
Good point that acceleration is also technical. It's just sort of silly to ask about misconceptions when the people he's asking don't even know what the words mean.
I would have liked it better if he had asked something about their positions and speeds, which are "layman" concepts. (I'm finding it hard to come up with an example, because most of my examples depend on the reference frame)
I enjoyed it anyway, from my nontechnical perspective.
Willoughby Krenzteinburg I wouldn't say acceleration and force are too different because actually as Newton states F=ma, they are very related. Also I think what Luke Palmer meant is that acceleration is easier to expireience in everyday life as compared to force which is a more abstract and difficult definition to imagine.

This might not be best but you are definatly the best

Similarly, they're all twowords.
I think it would have been easier to say that the forces are the same but due to (sigma) F=ma larger masses experience less acceleration if acted on by forces of the same magnitude.
Still doesn't make sense...1) would an amoeba pull on the sun with a force equal to the sun? 2) would a million amoebas each pull with the force of the sun therefore combined they're pulling with a total force of a million suns? 3) would an amoeba next to the sun have the same effect as a sun next to the sun? 4) if an amoeba pulls on the sun with an equal and opposite force, shouldn't the sun pull with the gravitational force of an amoeba?
@@localverse I'll just drop you a hint.... Remember G(M.m)/r^2 ?
Add to that F = ma and the concept of inertia and the reason should be evident.
Marino Hernandez
1) Yes, same force different acceleration
2) Yes
3) No, two suns pulling on each other exert a larger force.
4) Yes it does but ONLY on the amoeba. Again remember force and acceleration are different. They have the same force but because the sun is so massive it barely accelerated whereas the amoeba will accelerate much faster.
@@hopp2184 it still isn't clicking...#1 says the amoeba exerts sun-identical force that isn't enough to affect sun and #3 says an actual sun has a larger force...then #4 also seems contradictory because it says an amoeba-identical force by the sun would pull the amoeba (because the sun is massive) but #2 says that a combined force of a million suns (by a million amoebas) wouldn't pull on the sun as though there were an actual million suns
Marino Hernandez it’s great that you are curious and willing to understand! Think about it using Newton’s law of gravity:
F = G * m1 * m2 / r^2
This law says that any two objects exert the same gravitational FORCE on each other. However Force = mass * acceleration so objects with a larger mass have a smaller acceleration to “compensate” for the same force.
Mathematically you can think that
a=F/m
So a larger mass means smaller acceleration but still same force.
#1 This you seem to understand. Same force but different acceleration.
#3 Newton’s law of gravity is
F = G * m1 * m2 / r^2
If you increase the mass of one object then the force becomes larger on BOTH objects. So two suns attract at a greater gravitational force than one sun and one amoeba. But they might accelerate differently.
#2/4 remember Newton’s law of gravity? In it is the term m1 * m2. If an amoeba has mass m1 and the sun has mass m2 then the mass of 1 million suns gives a different force than 1 million amoebas.
I hope this has helped you :)

It was 2011, so he would be 28 years old :)
Somethings very young with you if you have a beard at the age of 12

You are really cool to do videos like this! I'm a bit interested in physics and now I learned so many things, like how does light work and what is inertia. Thanks!
Ye haven't bitten the dust yet, mate?
Me doing A level physics: I’m something of a physicists myself

Damn Derek you look way different without your beard
Clear enough and although it's ten years later, some reference to the inverse square formula in this particular context would have been interesting.
Anyone watching this in 2020?
